Dolby Vision now possible through MP4 Mux.

[Grencola]

Just to say it’s easy enough to string the three commands together into a basic shell script. Which takes the file as an argument. That’s what I’m doing now.

Yea, it's definitely not too complicated. I'm trying to make a one-click tool that converts an m2ts file all the way to a single-layer mp4 with lpcm 7.1 audio. issue I'm having is running dvdfab from a command line gets tricky while it's part of an integrated shell. dual layer is no problem since it's not needed. I was giving an option at startup of whether you want single layer or dual layer and then it goes to work. I wasn't going to bother with single at all since I thought dvdfab was faking dv, but the comparisons are so close to the real thing that it's worth it for people with shields / firesticks etc who don't have an x700 or a compatible tv usb player.

I see. Interesting if there’s some uncertainty over whether single layer DV from dvdfab is fake or not.

If it turns out to be a lossless DV conversion, it sure would be nice to be able to play these one day via Infuse on my Apple TV.

As long as there’s uncertainty though I feel much better about putting my money into an X700 and playing the original DV data effectively untouched (albeit repackaged).

[built_to_chill]

here's what is supported with the x700:

MP4 DV (SL & DL) + lpcm 7.1 = play perfectly fine. (subtitles dont work)
M2TS / TS + atmos = HDR10 only but atmos is supported.
MKV + atmos - HDR10 but atmos not supported (because the core is separated)
MKV + DTS-X / DTSHD = HDR10 and all the DTS family is supported.
Burned ISO = Dolby vision + atmos supported. (latest Tsmuxer can now create compliant DV bluray structure)https://forum.doom9.org/showthread.php?t=176668&page=16
no cinavia... But i only use it for DV mp4 remux, I wish there was a device that can do it all......
I use my HTPC for HDR10 and the new Shield for everything that is streaming....Netflix in DV + Atmos.. amazon, movies anywhere, vudu. etc...
Sorry for my english...

Hi there - I took a look at TSMuxer and it seems it can take various things (including mkv and i believe MP4) as input, and output an ISO. Just curious if you’re suggesting above this could be a route to getting Dolby vision and Dolby Atmos playback on the X700 when starting with an mkv?

Or whether this would require re-ripping everything to ISO using makemkv?

yes you can create a DV ISO from MKV using the latest tsmuxer but you'll have to process Atmos with eac3to first because tsmuxer wont accept ATmos without an AC3 core.

When a movie compress very well(CRF 14 or better) that's what i do. I re-encode the HDR10 layer to fit a BD-50 and then use tsmuxer to build a new iso with DV and Atmos and then i burn it.
I did that with a couple (about10) of movies and the x700 play my custom iso properly.

unfortunately I highly doubt this will work. the secondary dolby vision track on uhd discs is an hevc layer, just like the main layer. when mp4muxer (or dvdfab) makes an mp4 it uses the dvhe (dolby vision high efficiency) codec. the dolby vision metadata is now hardcoded with the mp4 container, and not the actual file inside. the same goes with if dolby makes a ts file - the dvhe exists only within that container. as soon as you demux the contents, or remux into a different container, you completely lose all dolby vision information and are left with an hdr10 base file only. in order to remux a dv mp4 to ts (for atmos I assume) and retain dv, you would need to extract the el+rpu data using one of Dolby's officially licensed PSU workstations. you would then have to re-author a ts file using proprietary licensed dolby tools, like it does for their sample videos. none of this is currently possible with 3rd-party hardware and software.

well it looks like they made it work. https://forum.doom9.org/showthread.php? ... ost1902124

ya been following closely! there's a good chance I stand corrected unless they paid for a license? also I can't wait to see if this works with truehd+atmos properly, and which devices are compatible..

definitely going to test my x700 and my shield tonight.

Many thanks for clarifying. Ah - if I follow - you have to literally burn to disc to get the X700 to play these.

I had been playing with eac3 to try and make m2ts files of my Atmos mkvs. So far it hasn’t run successfully but I am running it via wine on Ubuntu.

On the plus side I think the X700 effectively does DV auto switching for video files. With DV set to
on and playing an HDR10 mkv just now it did not play in forced Dolby vision. That’s great if don’t have to keep turning it on and off like you do for the actual discs.

Yes but the x700 does not support atmos in an mkv container because the AC3 core is missing. So you need the m2ts file for Atmos and if you let DV turned on, you get fake DV.

I dont know the exact cmd-line or anything about ubuntu but its very easy with the EAC3to GUI

That's awesome. Thanks also for listing the capabilities and limitations of the X700. Do you know if the X700 can play 3D Blu-ray backups as well in either M2TS, TS, and/or MKV format?

From your prior posts, it sounds like the X700 drops the MKV Atmos track due to the way in which the MKV is assembled?

the shield only supports dv profile 5. are you using the plex beta? I'm sure you are, but just in case, it's the only version that supports single layer dv.

I have a Vizio PX 75, I thought for sure it would work since the dolby ts test samples play just fine. it's not earc anyway though so it doesn't matter, as nothing would be gained.

one thing is concerning, and it could be the disc you tried, but how come the atmos track says lossy under compression mode, with a bitrate of only 640kbps / max 7134kbps and an ac3 mlp? every disc I've been checking says lossless compression with a bitrate around 5000+kbps/ max 8000+kbps and full thd mlp. it's like it's some weird atmos, that's not even eac3 dd+ atmos, but based on just ac3 instead or something. doesn't seem right to me.

what's also interesting is the main video layer says dolby vision now as well as the secondary layer. it's like it's doing a mixture of what dvdfab does to single layer mp4s but also keeping the 2nd video track. this should be fine though, since it has the el+rpu and the full second layer, just weird why it applies it like that.

the shield only supports dv profile 5. are you using the plex beta? I'm sure you are, but just in case, it's the only version that supports single layer dv.

yes, latest beta. I thought it would at least play the HDR10 layer but nop, black screen. the single layer mp4 works.
if I have more time tomorrow night, I'll try to remux the dvdfab single layer file to TS and play it with the shield.

I have a Vizio PX 75, I thought for sure it would work since the dolby ts test samples play just fine. it's not earc anyway though so it doesn't matter, as nothing would be gained.

it's a very cheap tv(M50-E1) that I use with my main PC. I'm not surprised that it doesn't work because most of the DV mp4 also plays in HDR10 only. it looks like it can't play the one with FEL DV.
surprising that it didn't play on the C8 though.
